Home Appliances Twisted Nematic 300 - 500cd/M2 Display Lcd Tn Panel

TN Displays for Home Appliances | Energy-Efficient, High Contrast, Durable Design

We specialize in manufacturing high-performance TN (Twisted Nematic) LCDs with COB (Chip-on-Board) encapsulation, tailored for testing instruments requiring reliable monochrome displays. Our displays excel in harsh environments, combining sharp contrast, low power consumption, and robust durability. From medical devices to industrial controls, we deliver solutions optimized for clarity, longevity, and seamless integration.

Key Technical Specifications

1. Core Display Performance

   • Display Mode: Configurable as Normally White Transmissive or Positive/Negative Contrast with static contrast ratio ≥800:1 for stable readability.

   • Driving Scheme: Supports 1/4 Duty, 1/3 Bias and custom driving modes to match instrument refresh rates (0.5Hz~50Hz).

   • Brightness & Uniformity: Adjustable 300-500 cd/m² brightness with ±10% uniformity, adaptable to low-light labs or high-ambient factories.

   • Viewing Angle: Effective 80° vertical/horizontal视角 (CR≥10) for multi-angle monitoring in testing equipment.

2. Environmental Resilience

   • Temperature Range: Operates at -20°C~70°C (storage: -30°C~80°C), ensuring stability in thermal chambers or outdoor instruments.

   • Vibration Resistance: Customizable anti-vibration design (5-500Hz frequency resistance) for machinery-mounted applications.

3. Power Efficiency

   • Low Voltage Operation: 3.0-5V DC input compatible with battery-powered portable devices.

   • WLED Backlight: 30,000-hour lifespan (≥50% brightness retention), minimizing replacement costs.

Customization Options

1. Interface & Integration

   • Flexible Connectors: Choose from metal pins, FPC cables, or LVDS interfaces with EMI shielding for signal integrity.

   • Touchscreen Upgrade: Optional resistive/capacitive touch layers for interactive instrument panels.

2. Structural Robustness

   • COB vs. COG: Enhanced dust/water resistance (IP54 optional) and shock absorption vs. conventional COG modules.

   • Modular Design: Replaceable backlight/driver units to streamline maintenance.

3. Compliance & Safety

   • Certifications: Pre-configured for CE, RoHS, and ISO13485 (medical-grade upon request).

Target Applications

• Medical: Patient monitors, diagnostic equipment

• Industrial: Process control panels, portable meters

• Laboratory: Precision measurement devices, environmental testers

Service Commitment

• Prototyping: Expedited sample delivery upon request (design-dependent).

• Lead Time: Production lead times tailored to project specifications.

• Support: Comprehensive post-sales assistance for technical integration and troubleshooting.
